Artificial functional spinal implant unit system and method for use

Abstract

A stabilization system for a human spine is provided comprising at least one dynamic interbody device and at least two dynamic posterior stabilization systems. The dynamic posterior stabilization system may be coupled on contralateral sides of vertebrae. In some embodiments, a bridge may couple a dynamic interbody device to a dynamic posterior stabilization system.

Description

PRIORITY CLAIM

[0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 634,950 to Gordon et al., filed on Aug. 5, 2003 and entitled “Artificial Functional Spinal Unit Assemblies”, which is incorporated herein by reference.BACKGROUND

[0002] 1. Field of the Invention

[0003] Embodiments of the invention generally relate to functional spinal implant assemblies for insertion into an intervertebral space between adjacent vertebrae of a human spine, and reconstruction of the posterior elements to provide stability, flexibility, and proper biomechanical motion. More specifically, embodiments of the invention relate to artificial functional spinal units including an artificial intervertebral implant that can be inserted via a posterior surgical approach and used in conjunction with one or more dynamic posterior stabilization systems to approach an anatomically correct range of motion and segmental stiffness. Embodiments of the invention may also be inserted v...
